[0037] Refer to Figures 1 to 5 The sensor assembly of the utility model will be described below.

[0038] As Figures 1 to 3 Indicated, the sensor assembly of the utility model embodiment, including base 100, first sensor 200 and ejector 300, first sensor 200 has the hinge side 210 and the movable side 220 that are opposite each other, the hinge side 210 is rotatably connected to base 100;Ejector 300 is fixed to base 100;Ejector 300 has elongation state and shortening state;In the case where ejector 300 is in elongation state, ejector 300 supports movable side 220, so that first sensor 200 is inclined relative to base 100;In the case where ejector 300 is in shortening state, first sensor 200 is housed in base 100.

[0039] In the process of ejector 300 elongation, the force of ejector 300 is used to make movable side 220 move towards the direction away from base 100;In the case where ejector 300 is in elongation state, ejector 300 supports movable side 220, and the hinge side 210 is rotatably connected to base 100, so that first sensor 200 is inclined relative to base 100, so that first sensor 200 can better carry out data acquisition work;In the case where ejector 300 is in shortening state, ejector 300 no longer supports movable side 220, and movable side 220 resets, so that first sensor 200 is housed in base 100, to reduce the overall size of the sensor assembly, avoid the sensor assembly occupies too large space.

[0040] The base 100 plays a bearing and housing role for the first sensor 200; the hinged side 210 is rotationally connected to the base 100, and the movable side 220 is located on the opposite side of the hinged side 210, and the movable side 220 can be close to or away from the base 100, so that the first sensor 200 rotates relative to the base 100. The first sensor 200 is housed in the base 100, which can be that the first sensor 200 is arranged in adhesion to the side wall of the base 100, for example, the first sensor 200 can be flat as a whole, and the first sensor 200 arranged in adhesion to the side wall of the base 100 can greatly reduce the size of the sensor assembly in the horizontal direction; or the first sensor 200 can be housed in the interior of the base 100, so as to reduce impurities such as dust and water vapor into the first sensor 200, thereby prolonging the service life of the first sensor 200.

[0041] In some embodiments, the first sensor 200 includes one or more of a rain sensor and a light sensor.

[0042] The rain sensor (also called a raindrop sensor or a rainwater sensor) is a sensor for detecting rainfall, and the data of rainwater can be obtained through the rain sensor, so as to determine whether it is raining and the size of the rainfall. The light sensor generally refers to a device that can sensitively sense light energy from ultraviolet light to infrared light and convert the light energy into an electrical signal; the data of light can be obtained through the light sensor, so as to determine the sunshine condition.

[0043] As shown in Figure 1 The first sensor 200 is inclined relative to the base 100, which is the use state of the first sensor 200, and is conducive to the first sensor 200 receiving external rainwater or light energy, for example, the first sensor 200 maintains an inclined state, which is conducive to rainwater falling on the rain sensor, so as to improve the accuracy of detection of the first sensor 200. The first sensor 200 is housed in the base 100, which is the housing state of the first sensor 200.

[0044] The ejector 300 can be switched between the elongated state and the shortened state quickly through the ejection and reset of the ejector 300, and then the first sensor 200 can be quickly switched between the use state and the housing state.

[0045] Generally, the ejector 300 can be a cabinet door rebounder, which is an automatic opening or closing device for a cabinet door, commonly used in designs without handles, and the opening mechanism is triggered by pressing the cabinet door. The function of the cabinet door rebounder is to use certain physical principles to enable the cabinet door to automatically rebound or push the door open after being subjected to slight pressure.

[0046] The cabinet door rebounder generally comprises a pressing assembly, a mechanical spring, a supporting structure and a locking assembly; the pressing assembly is used for triggering the action of the cabinet door rebounder, the mechanical spring is used for storing energy, and the mechanical spring is compressed when pressed and provides a pushing force when released; the locking assembly can ensure that the cabinet door stays at a certain position or has a damping effect to avoid the cabinet door from being opened or closed too quickly and bring an unstable experience. The cabinet door rebounder can have various structures, which are not listed one by one here, and can be specifically referred to the cabinet door rebounder disclosed in the Chinese patent document with the publication number CN217581766U.

[0047] The ejector 300 is arranged between the first sensor 200 and the base 100. In operation, the first sensor 200 can be pressed to transmit a force to the ejector 300, so that the ejector 300 is ejected to an elongated state, and the first sensor 200 is tilted relative to the base 100. In storage, the first sensor 200 is pressed again to transmit a force to the ejector 300, so that the ejector 300 is ejected to a shortened state, and the first sensor 200 is stored in the base 100.

[0048] As shown in Figures 2 to 3 In some embodiments, the base 100 has a mounting groove 110, and the hinged side 210 is rotationally connected to the side wall of the mounting groove 110, so that the first sensor 200 can be stored in the mounting groove 110. The ejector 300 is arranged at the groove bottom of the mounting groove 110 and is used to push the movable side 220 out of the slot of the mounting groove 110, so that the first sensor 200 in the mounting groove 110 can be extended out of the slot of the mounting groove 110 under the action of the ejector 300, facilitating the first sensor 200 to detect the rain or light in the environment.

[0049] As shown in Figures 2 to 3 In some embodiments, the hinged side 210 is provided with a rotating shaft 211, and the hinged side 210 is rotationally connected to the side wall of the mounting groove 110 through the rotating shaft 211. The sensor assembly further comprises a reset member 400 connected to the base 100 and the rotating shaft 211 and sleeved outside the rotating shaft 211.

[0050] In the case that the ejector 300 is in the elongated state, the reset member 400 is deformed and stores energy. In the case that the ejector 300 is in the shortened state, the reset member 400 releases the elastic force, which helps the first sensor 200 to be stored in the base 100. The reset member 400 is generally a torsion spring. Two rotating shafts 211 can be provided, one rotating shaft 211 is arranged at one end of the hinged side 210, and the other rotating shaft 211 is arranged at the other end of the hinged side 210 to improve the stability of the rotation of the hinged side 210. Correspondingly, two reset members 400 can be correspondingly arranged.

[0051] AsFigures 1 to 3 As shown in some embodiments, the ejector 300 is arranged at the middle of the first sensor 200 along the length direction of the first sensor 200 (e.g. the a direction in FIG. 1), which is conducive to the ejector 300 applying force to the first sensor 200 and further improves the stability of the rotation of the first sensor 200. During the process of the ejector 300 switching from the shortened state to the elongated state, the ejector 300 can directly act on the middle of the first sensor 200, which is conducive to the ejector 300 pushing the first sensor 200 to rotate, so that the first sensor 200 is inclined relative to the base 100. Figure 1

[0052] As shown in some embodiments, the hinged side 210 is located on the side of the movable side 220 away from the bottom of the base 100. In the case that the ejector 300 is in the shortened state, the ejector 300 no longer supports the first sensor 200. Since the hinged side 210 is located on the side of the movable side 220 away from the bottom of the base 100, the first sensor 200 is subjected to its own gravity, which promotes the movable side 220 to move towards the base 100, so that the first sensor 200 automatically swings from the inclined state to the vertical state, i.e. the first sensor 200 is drooping, and further makes the first sensor 200 be stored into the base 100. Figures 2 to 3

[0053] As shown in some embodiments, the sensor assembly includes a second sensor 600, and the base 100 has an inlet 120, an outlet 130 and a mounting space 140. The inlet 120 and the outlet 130 are respectively connected to the mounting space 140, and the second sensor 600 is installed in the mounting space 140. Figures 2 to 3

[0054] The mounting space 140 provides a physical barrier for the second sensor 600, reducing the entry of impurities such as water vapor and dust into the second sensor 600. Sound waves, gases and other environmental factors can enter the mounting space 140 through the inlet 120, so that the second sensor 600 can detect the noise, formaldehyde content and other conditions of the environment. The air in the environment enters the mounting space 140 through the inlet 120 and flows out through the outlet 130, so that an air passage is formed inside the base 100, improving the accuracy of detection.

[0055] The base 100 can include a housing 150 and a cover 160, wherein the mounting space 140 is formed in the housing 150, and the housing 150 has an opening 151 connected to the mounting space 140, and the cover 160 covers the opening 151. During installation, the second sensor 600 is installed in the mounting space 140, and the cover 160 is covered. The arrangement of the cover 160 facilitates the maintenance of the second sensor 600.

[0056] ​​​In some embodiments, the sensor assembly further comprises a PCB board, the first sensor 200 and the second sensor 600 are electrically connected with the PCB board, and the first sensor 200 and the second sensor 600 can be controlled through the PCB board; wherein the PCB board can be arranged in the mounting space 140, and the second sensor 600 can be mounted on the PCB board.

[0057] As shown in FIG. 1, in some embodiments, the sensor assembly further comprises a decorative plate 500, and the decorative plate 500 is fixed to one side of the base 100; the decorative plate 500 plays a role of decoration and improves the overall aesthetics of the sensor assembly; the decorative plate 500 has a working window 510, and part of the first sensor 200 can extend out of the working window 510 to obtain data of rainwater or illumination. Figure 2

[0058] As shown in FIG. 1, in some embodiments, the sensor assembly further comprises a decorative plate 500, and the decorative plate 500 is fixed to one side of the base 100; the decorative plate 500 plays a role of decoration and improves the overall aesthetics of the sensor assembly; the decorative plate 500 has a working window 510, and part of the first sensor 200 can extend out of the working window 510 to obtain data of rainwater or illumination. Figure 4

[0059] As shown in FIG. 1, in some embodiments, the inlet 120 and the working window 510 are located on the same side of the base 100, and air in the environment where the sensor assembly is located can enter the inside of the mounting space 140 through the inlet 120 for the second sensor 600 to detect the air to be measured; part of the first sensor 200 can extend out of the working window 510 to obtain data of rainwater or illumination. By arranging the inlet 120 and the working window 510 on the same side of the base 100, the sensor assembly can detect the air on the same side of the base 100, thereby reducing detection errors. Figure 2

[0060] As shown in FIG. 1, in some embodiments, the working window 510, the inlet 120 and the outlet 130 are arranged on the decorative plate 500, and the working window 510 is located between the inlet 120 and the outlet 130, which facilitates air intake and exhaust, and at the same time, can increase the distance between the inlet 120 and the outlet 130 as much as possible, thereby increasing the flow path of the gas inside the base 100, which is conducive to the detection work of the second sensor 600. Figure 2

[0061] As shown in FIG. 1, in some embodiments, the second sensor 600 comprises one or more of a formaldehyde sensor 610, a noise sensor 620, a temperature and humidity sensor 630, a carbon dioxide sensor 640, a TVOC sensor 650 and a PM2.5 sensor 660. Figure 5

[0062] ​​​​​The formaldehyde sensor 610 is used to detect the concentration of formaldehyde in the air. For example, the formaldehyde sensor 610 can be a semiconductor sensor that judges the formaldehyde concentration based on the principle of resistance change of semiconductor materials; when formaldehyde gas contacts the sensor surface, formaldehyde molecules react with the semiconductor material, causing the charge distribution on the material surface to change, thereby changing the resistance; the change in resistance is directly proportional to the concentration of formaldehyde, and by measuring the change in resistance, the sensor can determine the concentration of formaldehyde in the air.

[0063] The noise sensor 620 converts the sound wave signal into an electrical signal, and then judges the size of the noise according to the strength of the electrical signal. For example, the noise sensor 620 can be a piezoelectric sensor that detects sound waves through piezoelectric materials such as quartz; the sound wave vibration causes the piezoelectric material to deform, thereby generating a voltage signal, and the voltage signal is directly proportional to the noise intensity.

[0064] The temperature and humidity sensor 630 can measure the temperature and humidity in the environment and convert them into an electrical signal. For example, the temperature and humidity sensor 630 can be a capacitive temperature and humidity sensor 630 that detects humidity and temperature by measuring changes in capacitance.

[0065] The carbon dioxide sensor is used to detect the concentration of carbon dioxide in the air.

[0066] The carbon dioxide sensor 640 can be an electrochemical sensor that measures gas concentration by using the chemical reaction of carbon dioxide on the electrode to generate a change in current or voltage; carbon dioxide reacts with the electrode of the electrochemical sensor to produce an electrochemical reaction, and the change in current or voltage is directly proportional to the concentration of carbon dioxide, and the electrochemical sensor estimates the gas concentration by measuring the change in current or voltage.

[0067] The TVOC sensor 650 is used to detect the concentration of total volatile organic compounds (TVOCs) in the air; the TVOC sensor 650 can be an electrochemical sensor, and the gas reacts with the electrode inside the sensor to produce a change in current or voltage related to the concentration of TVOCs.

[0068] The PM2.5 sensor 660 is a sensor used to detect the concentration of fine particulate matter (PM2.5) in the air. The PM2.5 sensor 660 can be a light scattering sensor that emits a beam of light (such as infrared light or laser light) and then measures the intensity of light scattered on the surface of the particulate matter; the larger the particulate matter or the higher the concentration, the greater the intensity of scattered light, and by measuring the change in intensity of scattered light, the sensor can estimate the concentration of PM2.5 in the air.

[0069] In some embodiments, the PM2.5 sensor 660 is internally provided with a fan, which functions to introduce air into the PM2.5 sensor 660 to detect PM2.5 particles in the air; the fan can ensure continuous flow of the air sample, ensuring the accuracy of the data; since the second sensor 600 is installed in the installation space 140, the fan can bring air into the installation space 140, which is more conducive to the formaldehyde sensor 610, the noise sensor 620, the temperature and humidity sensor 630, the carbon dioxide sensor 640 or the TVOC sensor 650 in the installation space 140 detecting the real-time conditions of the environment in which the sensor assembly is located, to ensure the accuracy of the data. Generally, the fan includes a micro motor and a fan blade, which is driven to rotate by the micro motor, thereby driving the air flow.

[0070] The utility model discloses at least one of formaldehyde sensor 610, noise sensor 620, temperature and humidity sensor 630, carbon dioxide sensor 640, TVOC sensor 650 and PM2.5 sensor 660 is set up to detect at least one of formaldehyde, noise, temperature and humidity, carbon dioxide, TVOC and PM2.5 content in the environment, to increase the function of sensor assembly, to accurately judge the environment by obtaining multiple aspects of parameters in the environment.
